Chauvin C.A 6505

The Chauvin C.A 6505 megohmmeter is a portable instrument housed in a rugged field case with lid and operates on either battery or line power. It makes voltage, insulation, and capacitance measurements. As soon as the switch is set to an insulation measurement position, the instrument automatically measures the presence of any AC/DC voltage. This voltage is measured at all times and indicated on the small display unit. The CA6505 automatically determines AC or DC: the AC measurement is an RMS value. Insulation is sensitive to temperature and humidity variations. In addition, measurement is affected by the appearance of disturbance currents. To overcome these effects, long-term measurements must be performed and the PI and DAR coefficients must be calculated. They will then allow qualification of the insulants and their ageing. FEATURES Automatic voltage measurement, Automatic detection of the presence of an external AC or DC voltage on the terminals. Simple user interface, Calculation of the PI and of the DAR. Fuse protection of the instrument, with detection of a defective fuse. Operator safety thanks to the automatic discharging of the device tested. Automatic power-down of the instrument to extend battery life. Indication of the battery charge condition. Large backlit LCD display unit with many announciators for very easy reading.
